Ok so going off the topic of piccolos in Irish music again, I recently found a Pipeau for sale in France.
These come up in ebay now and again and are french made conical six holes whistles some with flageolet like beaks, fake side blown fipples, or standard whistle heads. They are made of metal or celluloid.
Here is the one I purchased, it's not here yet:
This one is branded Atlas hopefully a D but the seller never gave me dimensions despite my asking.
More to follow...........
